Prometheus（普罗米修斯）是一套开源的监控&报警&时间序列数据库的组合，由 SoundCloud 公司开发。

Prometheus 基本原理是通过 HTTP 协议周期性抓取被监控组件的状态，这样做的好处是任意组件只要提供 HTTP 接口就可以接入监控系统，不需要任何 SDK 或者其他的集成过程。这样做非常适合虚拟化环境比如 VM 或者 Docker 。

Prometheus 应该是为数不多的适合 Docker、Mesos、Kubernetes 环境的监控系统之一。

1.拉取镜像

docker pull prom/prometheus

2.创建prometheus目录，新增prometheus.yml文件，用于指定设置docker地址

mkdir -p /home/prometheus

3.创建prometheus容器，指定端口、名称、挂载目录、设置时区

docker run -d -p 9090:9090  -v /home/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

4.访问页面

120.48.54.67:9090

springboot配置

在spring boot工程中引入actuator的起步依赖，以及micrometer-registry-prometheus的依赖。

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
        <groupId>io.micrometer</groupId>
        <artifactId>micrometer-registry-prometheus</artifactId>
<version>1.6.4</version>
</dependency>

application.yml暴露prometheus的接口；暴露metrics.tags，和spring.application.name一致。

server:
  port: 8087
spring:
  application:
    name: swaggerDemo
management:
  endpoints:
    web:
      exposure:
        include: "*"
  metrics:
    tags:
      application: ${spring.application.name}

回到prometheus目录下面修改prometheus.yml：

# my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=` to any timeseries scraped from this config.
###以下内容为SpringBoot应用配置
  - job_name: 'swaggerDemo'
    scrape_interval: 5s
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets: ['120.48.54.67:8087']
